Clinician programming system and method

ABSTRACT

In a method for programming an implantable device, an input is received at a user interface on a tablet-style clinician programmer. A first display signal is generated on the clinician programmer that updates content on a first display based on the received user input. The first display has a first size. A second display signal is generated for transmission to a secondary unit having a second display separate from the clinician programmer. The second display has a second size larger than the first size. The generating of the second display signal includes enhancing the content of the second display signal to provide a clear image on the second size display. The second display signal is transmitted from the clinician programmer to the second display.

PRIORITY DATA

The present application is a divisional patent application of U.S.patent application Ser. No. 13/600,875, filed on Aug. 31, 2012, entitled“Clinician Programming System and Method”, now U.S. Pat. No. 8,903,496,issued Dec. 2, 2014, the disclosure of which is hereby incorporated byreference in its entirety.

FIELD OF THE INVENTION

This disclosure is directed to an external monitor connection for aclinician programmer.

BACKGROUND

Neurostimulation devices deliver therapy in the form of electricalstimulation pulses to treat symptoms and conditions, such as chronicpain, Parkinson's disease, or epilepsy, for example. Implantableneurostimulation devices, for example, deliver neurostimulation therapyvia leads that include electrodes located proximate to the muscles andnerves of a patient.

Clinician programmers are used to control and program theneurostimulation devices with stimulation sequences to treat symptomsand conditions. These clinician programmers and devices of their typeare relatively small to allow for easy transportation and storage. Theportability has its price, however. It is difficult for more than oneperson to view the relatively small screen of a handheld programmer.People would have to crowd around the device to be able to attempt tosee what is happening on the screen.

Further, even though the clinician programmer is portable, there aresome areas where its use may be restricted. For instance, a clinicianprogrammer may be covered under the drapes while a sales representativeis talking to the patient. The clinician programmer thus may not bevisible to the physician. As another example, the clinician programmermay not be a sterile device and cannot be taken into the sterile fieldin an operating room. Since the clinician programmer must remain outsideof the sterile field, the physician is unable to read the screen whileperforming the procedure. Accordingly, the physician must verballyinteract with and rely on someone (an external operator), who acts ashis eyes and hands controlling the programmer outside of the sterilefield. The situation could also be reversed, where the physician isdoing the programming, and the staff is observing his/her actions, forexample, talking to the patient at the head end of the surgery table. Inany case, requiring an extra person results in additional time for theprocedure to be completed as a result of the verbal communication of theprogramming device state and adjustments to be made between thephysician and the external operator. The verbal interchange may alsoresult in miscommunication which will add additional time to completethe procedure and possibly result in more severe consequences.

The present disclosure is directed to devices, systems, and methods thataddress one or more deficiencies in the prior art.

SUMMARY

This disclosure is directed to a patient programmer in communicationwith an external monitor that helps to alleviate the problems set outabove. When demonstrating the device, for example, the screen can bedisplayed on a large monitor for group viewing. In addition, when usedfor a procedure within an operating room, the programmer can be keptoutside the sterile field, but its user interface can be made availablefor viewing by the physician and others through a projector or largescreen monitor. In many cases, the external screen may be the onlyscreen that the physician can see, because the clinician programmer isunder the cover or tucked away.

DETAILED DESCRIPTION

The following disclosure provides many different embodiments, orexamples, for implementing different features of various embodiments.Specific examples of components and arrangements are described below tosimplify the present disclosure. These are, of course, merely examplesand are not intended to be limiting. In addition, the present disclosuremay repeat reference numerals and/or letters in the various examples.This repetition is for the purpose of simplicity and clarity and doesnot in itself dictate a relationship between the various embodimentsand/or configurations discussed.

The devices, systems, and methods described herein introduce an improvedway for controlling and programming an implanted medical device. Theyuse a clinician programmer (“CP”) with a first display electricallycoupled (for example, coupled in a wired or wireless manner) to a seconddisplay disposed for viewing by others than the clinician performing theprogramming. In one example, the CP may be outside a sterile field, butmay be in communication with a display viewable to others who are withinthe sterile field. This may be particularly helpful to surgeons whoperform surgeries and must issue instructions to a programming clinicianto direct or control an implant in a certain manner. The surgeon maylook at the second display and see the settings and programming as itoccurs on the CP, instead of relying merely on verbal feedback from theprogramming clinician. This may streamline the surgery and since thesurgeon can now see the clinician programming screen, may help assurethe surgeon that his instructions are being carried out as requestedwithout relying solely on verbal feedback. This may reduce verbalcommunication errors between staff during programming. Accordingly, thismay provide a level of redundancy and risk management not achieved whenprogramming is performed with only a CP outside the sterile field. Inanother example, the CP sends information shown on its display to thesecond larger display for viewing by additional people. This may beparticularly helpful during training processes, when the clinician maybe instructing trainees or other clinicians in treatment techniques, forexample.

FIG. 1A is a side view of a spine 10, and FIG. 1B is a posterior view ofthe spine 10. FIG. 1B shows an exemplary electrical stimulator treatmentsystem 100 disposed to treat a spinal region for treating a symptom,such as chronic pain. The system includes an implantable pulse generator(IPG) 102 that delivers electrical stimulation therapy to the patient,and a CP 104.

Referring now to FIGS. 1A and 1B, the spine 10 includes a cervicalregion 11, a thoracic region 12, a lumbar region 14, and asacrococcygeal region 16. The cervical region 11 includes the top sevenvertebrae, which may be designated with C1-C7. The thoracic region 12includes the next twelve vertebrae below the cervical region 11, whichmay be designated with T1-T12. The lumbar region 14 includes the finalfive “true” vertebrae, which may be designated with L1-L5. Thesacrococcygeal region 16 includes nine fused vertebrae that make up thesacrum and the coccyx. The fused vertebrae of the sacrum may bedesignated with S1-S5.

Neural tissue (not illustrated for the sake of simplicity) branches offfrom the spinal cord through spaces between the adjacent vertebrae. Theneural tissue, along with the cord itself, can be individually andselectively stimulated in accordance with various aspects of the presentdisclosure. For example, referring to FIG. 1B, the IPG 102 is implantedinside the body. A conductive lead 108 is electrically coupled to thecircuitry inside the IPG 102. The conductive lead 108 may be removablycoupled to the IPG 102 through a connector, for example. A distal end ofthe conductive lead 108 is attached to one or more electrodes 110. Inthe example shown, the electrodes 110 are implanted adjacent to adesired nerve tissue in the thoracic region 12. The distal end of thelead 108 with its accompanying electrodes may be positioned beneath thedura mater using well-established and known techniques in the art.

The electrodes 110 deliver current drawn from the IPG 102, therebygenerating an electric field near the neural tissue. The electric fieldstimulates the neural tissue to accomplish its intended functions. Forexample, the neural stimulation may alleviate pain in an embodiment. Inother embodiments, a stimulator as described above may be placed indifferent locations throughout the body and may be programmed to addressa variety of problems, including for example but without limitation;prevention or reduction of epileptic seizures, bladder control, weightcontrol or regulation of heart beats.

It is understood that the IPG 102, the lead 108, and the electrodes 110may be implanted completely inside the body, or may have only one ormore components implanted within the body while other components remainoutside the body. When they are implanted inside the body, the implantlocation may be adjusted (e.g., anywhere along the spine 10) to deliverthe intended therapeutic effects of spinal cord electrical stimulationin a desired region of the spine. The IPG 102 in this system is a fullyimplantable, battery-powered neurostimulation device for providingelectrical stimulation to a body region of a patient. In someembodiments, an external pulse generator (EPG) is used. The EPG isidentical to the IPG but the connection is done through percutaneouswires (communication may still be wireless though). In the example shownin FIG. 1B, the IPG 102 is configured to provide neural stimulation tothe spine. However, in other embodiments, IPG 102 may be a differenttype of pulse generator, including, for example, a pacemaker, adefibrillator, a trial stimulator or any other type of medical device.Here, the IPG 102 is structurally configured and arranged for wirelessprogramming and control through the skin of the patient. Accordingly, itincludes a transmitter and receiver capable of communicating withexternal programming and control devices, such as the CP 104. It alsoincludes a rechargeable power source, such as a battery configured to bewirelessly recharged through the patient's skin when a charger isexternally placed in the proximity of the IPG 102.

The CP 104 is typically maintained in a health care provider'spossession and can be used to program the IPG 102 as a part of theimplantation treatment and later during office visits. For example only,the CP 104 can define the available stimulation programs for the IPG 102by enabling and disabling particular stimulation programs, can definethe actual stimulation programs by creating defined relationshipsbetween pulses, and perform other functions.

FIG. 2 is a block diagram showing an exemplary clinician programmingsystem 150. The programming system 150 includes the CP 104, the IPG 102,a secondary display unit 152, a patient feedback tool (“PFT”) 210, and asurgeon input device 212.

The CP 104 is, in one embodiment, a tablet-style device with a touchscreen and radios for communicating with active implantable medicaldevices, such as neurostimulators like the IPG 102. As can be seen inFIG. 2, the CP 104 includes a processor 160, memory 162, a userinterface 164, and a communication interface 166.

As shown in FIG. 2, the user interface 164 includes a primary displayscreen 168, an input mechanism 170, a speaker 172, and a microphone 174.The speaker 172 and the microphone 174 enable audio communicationbetween the CP 104 and the secondary display unit 152. For example, thespeaker 172 may be linked with a microphone 186 on the secondary displayunit 152, and the microphone 174 may enable communication with a speaker184 on the secondary display unit 152. As described below, this may beuseful when the CP 104 and the secondary display unit 152 are indifferent locations.

The communication interface 166 enables the CP 104 to communicate withother components of the clinician programming system 150. In theembodiment shown, the communication interface 166 includes a secondarydisplay communication interface 176 and a peripheral interface 178.These, along with other elements of the CP 104, are described in detailwith reference to FIG. 3.

FIG. 3 shows a block diagram of a more detailed construction of the CP104. Referring to FIG. 3, the CP 104 includes a printed circuit board(“PCB”) that is populated with a plurality of electrical and electroniccomponents that provide power, operational control, and protection tothe CP 104. The processor 160 is a controller for controlling the CP104, and indirectly programming, controlling, and responding to the IPG102, the secondary display unit 152, the PFT 210, and the surgeon inputdevice 212. In one construction, the processor 160 is an applicationsprocessor model i.MX515 available from Freescale Semiconductor. Morespecifically, the i.MX515 applications processor has internalinstruction and data caches, multimedia capabilities, external memoryinterfacing, and interfacing flexibility. Further information regardingthe i.MX515 applications processor can be found in, for example, the“IMX510EC, Rev. 4” data sheet; dated August 2010; published by FreescaleSemiconductor at www.freescale.com, the content of the data sheet beingincorporated herein by reference. Of course, other processing units,such as other microprocessors, microcontrollers, digital signalprocessors, etc., can be used in place of the processor 160.

The CP 104 includes memory 162, which can be internal to the processor160 (e.g., memory 305), external to the processor 160 (e.g., memory310), or a combination of both. The memory 162 stores sets ofinstructional information with stimulation control parameters that areavailable to be selected for delivery through the communicationinterface 166 to the IPG 102 for electrical stimulation therapy or tothe secondary display unit 152 for display to a plurality of individualsin the surgical area or elsewhere. Exemplary memory include a read-onlymemory (“ROM”), a random access memory (“RAM”), an electrically erasableprogrammable read-only memory (“EEPROM”), a flash memory, a hard disk,or another suitable magnetic, optical, physical, or electronic memorydevice. The processor 160 executes software that is capable of beingstored in the RAM (e.g., during execution), the ROM (e.g., on agenerally permanent basis), or another non-transitory computer readablemedium such as another memory or a disc. The CP 104 also includesinput/output (“I/O”) systems that include routines for transferringinformation between components within the processor 160 and othercomponents of the CP 104 or external to the CP 104.

Software included in the implementation of the CP 104 is stored in thememory 305 of the processor 160, RAM 310, ROM 315, or external to the CP104. The software includes, for example, firmware, one or moreapplications, program data, one or more program modules, and otherexecutable instructions. The processor 160 is configured to retrievefrom memory and execute, among other things, instructions related to thecontrol processes and methods described below for the CP 104. Forexample, the processor 160 is configured to execute instructionsretrieved from the memory 162 for establishing a protocol to control theIPG 102. Some embodiments include software modules configured to provideinstructions for accomplishing particular tasks handled by the CP 104.For example, the CP 104 includes a programming software moduleconfigured to generate a treatment or stimulation program based on inputreceived from a user of the CP 104. A secondary display software modulecontrols the signals and communication sent from the CP 104 to thesecondary display unit 152. Additional exemplary software will bedescribed in further detail below.

Since the secondary display screen 182 is larger than the primarydisplay screen 164 as described below, the secondary display softwaremodule may be configured to enhance the resolution or otherwise formator modify the display signal in a way that creates a clearer image ofthe content on the secondary display. This may ensure that a relativelyclear image is shown on a secondary screen having a larger screen sizethan that of the CP primary display screen 164, while not requiring ashigh resolution for the smaller primary display screen 164.

One memory shown in FIG. 3 is memory 310, which can be a double datarate (DDR2) synchronous dynamic random access memory (SDRAM) for storingdata relating to and captured during the operation of the CP 104. Inaddition, a secure digital (SD) multimedia card (MMC) can be coupled tothe CP for transferring data from the CP to the memory card via slot315. Of course, other types of data storage devices can be used in placeof the data storage devices shown in FIG. 3.

The peripheral interface 178 is configured, depending on the embodiment,to receive data or signals from the IPG 102, the PFT 210, and thesurgeon input device 212. Accordingly, it may include an implantcommunication interface, a PFT communication interface, and a surgeoninput device communication interface. The implant communicationinterface includes structure and components enabling the CP 104 to sendor receive information to and from the IPG 102. For example, it maycomprise a radio transceiver that enables one-way or two-waycommunication with the IPG 102. The interface 178 may include componentsfor wireless or wired communication and may be configured with any ofthe components discussed above with reference to the secondary displaycommunication interface 176. In one example, the implant communicationinterface 178 comprises a medical implant communication service (MICS)RF transceiver used to communicate with the IPG 102 to communicatedesired changes and to receive status updates from and relating to theIPG 102, such as battery status and any error information. In thisexample, the MICS RF transceiver utilizes a loop antenna for thecommunications with the IPG 102. Other antennas, such as, for example,dipole, chip antennas, or other antennas known in the art also may beused. The CP 104 may also include a programming interface used duringmanufacturing to load an operating system and program the CP 104.

The PFT communication interface and the surgeon input devicecommunication interface may include structure and components enablingthe CP to send and receive information to and from the PFT and thesurgeon input device. These interfaces may be similar to that of theimplant communication interface, or alternatively, may be otherwiseenabled. Depending on the embodiment, the PFT communication interfaceand the surgeon input device communication interface may be one or moreports for wired communication, such as universal serial bus (USB)connectivity 355, including a Type A port and a Micro-B port; a relatedport for supporting Joint Test Action Group (JTAG) or other plug-instyle port, or may be wireless using, for example, Wi-Fi portion 325 andBluetooth portion 330 that respectively include a Wi-Fi communicationinterface, a Bluetooth communication interface, an antenna switch, and arelated antenna all of which allows wireless communication following theWi-Fi Alliance standard and Bluetooth Special Interest Group standard.Of course, other wireless local area network (WLAN) standards andwireless personal area networks (WPAN) standards can be used with the CP104. Any other interface enabling communication between the CP 104 andthe PFT 120 or surgeon input device 212 may be used. In someembodiments, the interface 178 is the same as the interface 176.

The secondary display communication interface 176 includes multiplebi-directional radio communication capabilities. Specific wirelessportions included with the CP 104 are a Wi-Fi bi-direction radiocommunication portion 325, and a Bluetooth bi-direction radiocommunication portion 330. The Wi-Fi portion 325 and Bluetooth portion330 include a Wi-Fi communication interface, a Bluetooth communicationinterface, an antenna switch, and a related antenna all of which allowswireless communication following the Wi-Fi Alliance standard andBluetooth Special Interest Group standard. Of course, other wirelesslocal area network (WLAN) standards and wireless personal area networks(WPAN) standards can be used with the CP 104.

The CP 104 includes multiple communication portions for wiredcommunication. Exemplary circuitry and ports for receiving a wiredconnector include a port for supporting universal serial bus (USB)connectivity 355, including a Type A port and a Micro-B port, a portionand related port for supporting Joint Test Action Group (JTAG)connectivity 360, and a portion and related port for supportinguniversal asynchronous receiver/transmitter (UART) connectivity 365. Ofcourse, other wired communication standards and connectivity can be usedwith or in place of the types shown in FIG. 3.

The secondary display communication interface 176 includes the structureand components enabling the CP 104 to send or receive information to andfrom the secondary display unit 152. In one embodiment, the secondarydisplay communication interface 176 is integral with the CP 104 and isavailable along an edge, such as a lower edge, under a protective coverof the CP 104. In one embodiment, the secondary display communicationinterface 176 includes a HDMI port formed in a housing of the CP 104.The interface 176 may allow connection to the external secondary displayunit 152 via a micro High-Definition Multimedia Interface (HDMI) 370,which provides a compact audio/video interface for transmittinguncompressed digital data to the external display unit 152. The use ofthe HDMI connection 370 allows the CP 104 to transmit video (and audio)communication to the external display unit 152. This may be beneficialin situations where others (e.g., the surgeon) may want to view theinformation being viewed by a CP user. The surgeon typically has novisual access to the CP 104 in the operating room. The HDMI connection370 allows the surgeon to view information from the CP 104, therebyallowing greater communication between the clinician and the surgeon.For a specific example, the HDMI connection 370 can broadcast a highdefinition television signal that allows the surgeon to view the sameinformation that is shown on the LCD (discussed below) of the CP 104. Inaddition, as HDMI signals are compatible with DVI, the CP 104 can alsobe connected, with the proper cabling, to other external display devicesthat only support DVI input. In some embodiments, audio and video can beplayed independently. In other embodiments, audio and video can beplayed in a synchronized manner.

In another embodiment, the secondary display communication interface 176includes a wireless transmitter and receiver configured to wirelesslycommunicate with the secondary display communication interface 176. Inone example, it includes structure and encoding for Wi-Fi communication.In another example, it includes structure and encoding for Bluetoothcommunication. Additional wireless protocols are contemplated. In someexamples, the secondary display communication interface 176 is anetworking port on the CP that enables the CP 104 to communicate withthe secondary display unit 152 over a WAN, LAN, or other network,including the Internet.

The CP 104 includes three hard buttons: a “home” button 335 forreturning the CP to a home screen for the device, a “quick off” button340 for quickly deactivating stimulation, and a “reset” button 345 forrebooting the CP 104. The CP 104 also includes an “ON/OFF” switch 350,which is part of the power generation and management block (discussedbelow). In some embodiments, the “reset” button 345 may be eliminated,and the “ON/OFF” switch 350 can be used to remove all power when heldlong enough.

In FIG. 2, the CP 104 includes the primary display screen 168 arrangedfor viewing by the clinician operating the CP 104 and configured todisplay information relating to the programmer 104, the IPG 102, thesecondary display unit 152, the PFT 210, and/or the surgeon input device212. The input mechanism 170 permits a user to control images on thedisplay and to make selections within a limited scope, so as to controlthe relationships between different control aspects. In FIG. 3, theprimary display screen 168 and the input mechanism 170 are merged into atouch screen I/O device 375 for providing a user interface with theclinician. The touch screen display 375 can be a liquid crystal display(LCD) having a resistive, capacitive, or similar touch-screentechnology. It is envisioned that multitouch capabilities can be usedwith the touch screen display 375 depending on the type of technologyused. However, in place of a touch screen display, a computer keyboard,a standard pointing device, such as a mouse or trackball, or other inputdevices are also contemplated.

The CP 104 includes a camera 380 allowing the device to take pictures orvideo. The resulting image files can be used to document a procedure oran aspect of the procedure. For example, the camera 380 can be used totake pictures of barcodes associated with the IPG 102 or the leads 120,or documenting an aspect of the procedure, such as the positioning ofthe leads. Similarly, it is envisioned that the CP 104 can communicatewith a fluoroscope or similar device to provide further documentation ofthe procedure. Other devices can be coupled to the CP 104 to providefurther information, such as scanners or RFID detection. Similarly, theCP 104 includes an audio portion 385 having an audio codec circuit,audio power amplifier, and related speaker for providing audiocommunication to the user, such as the clinician or the surgeon.

The CP 104 further includes a power generation and management block 390.The power block 390 has a power source (e.g., a lithium-ion battery) anda power supply for providing multiple power voltages to the processor,LCD touch screen, and peripherals.

In one embodiment, the CP 104 is a handheld computing tablet with touchscreen capabilities. The tablet is a portable personal computer with atouch screen, which is typically the primary input device. However, anexternal keyboard or mouse can be attached to the CP 104. The tabletallows for mobile functionality not associated with even typical laptoppersonal computers.

In operation, the IPG 102 (which may also be an EPG) through the use ofthe implanted medical electrical leads 108, and specifically theelectrodes 110 (FIG. 1B), stimulates neurons of the spinal cord 10. TheIPG 102 selects an electrode stimulating configuration, selects astimulation waveform, regulates the amplitude of the electricalstimulation, controls the width and frequency of electrical pulses, andselects cathodic or anodic stimulation. This is accomplished by ahealthcare professional (e.g., a clinician), using the CP 104, settingthe parameters of the IPG 102. The setting of parameters of the IPGresults in a “program,” which is also referred to herein as a“protocol,” for the electrode stimulation. Programming may result inmultiple protocols that the patient can choose from. Multiple protocolsallow, for example, the patient to find a best setting for paresthesiaat a particular time of treatment.

Returning now to the block diagram in FIG. 2, the secondary display unit152 includes a relatively large display screen suitable for displayingsystem information to a surgeon or patient when used in the operatingroom, to a group of students, or to other groups. In one example, thesecondary display unit 152 is disposed within an operating surgical roomwhere it can be seen by a surgeon performing a surgery. The secondarydisplay unit 152 includes a display screen 182, a speaker 184, amicrophone 186, and a communication interface 188. It is understood thatthe speaker 184 and the microphone 186 are optional and may be omittedin some embodiments.

Because the CP 104 is a portable device and includes a relatively smallprimary display screen 168, it is not easily viewed by multiple peopleat a single time. However, the display screen 182 of the secondarydisplay unit 152 is sized larger than the display screen 168 of theprimary CP 104 and enables multiple people to simultaneously view thescreen and allows surgeons to see the IPG status or action taken by theCP. In one example, the display screen 182 is more than twice the sizeof the primary display screen 168 of the CP 104. One exemplary displayscreen 182 is sized with a diagonal measurement greater than about 22inches. Another exemplary display screen 182 is sized with a diagonalmeasurement greater than about 30 inches. Other sizes, both larger andsmaller are contemplated. The display screen, in some examples, is alarge monitor whose image is controlled entirely from the clinicianprogrammer 104. In one example it is a smart monitor configured toconvert information received from the clinician into a three-dimensionalimage and to display information in a three-dimensional manner.

The speaker 184 and microphone 186 are linked respectively with themicrophone 174 and the speaker 172 on the CP 104. As such, communicationis enabled between individuals proximate the secondary display unit 152and the individual proximate to and operating the CP 104. As indicatedabove, this may be useful when the CP 104 and the secondary display unit152 are in different locations. In one embodiment, the communication viathe microphones and the speakers on the CP 104 and the secondary displayunit 152 communicate over the same secondary display communicationinterface 176 and the CP interface 190. In other embodiments, they haveseparate communication channels, wired or wireless, for transmitting andreceiving information.

The communication interface 188 in the secondary display unit 152includes a CP interface 190 and a peripheral interface 192. The CPinterface 190 is configured, depending on the embodiment, to receivedata or signals from the secondary display communication interface 176on the CP 104. For example, the CP interface 190 may connect to thesecondary display communication interface 176 on the CP 104 via HDMIusing a Type D Micro to Type A HDMI connector. Alternatively, or inaddition to, the HDMI signals may be compatible with DVI. Thus, the CP104 can also be connected, with the proper cabling, to other externaldisplay devices that only support DVI input.

In one example, the secondary display unit is configured to display thesame information as the primary display screen 168 on the CP 104. Thismirroring of the screens 168, 182 enables a surgeon in an operating roomand the clinician who is operating the CP to see the same information,albeit in different locations.

The peripheral interface 192 is configured, depending on the embodiment,to receive data or signals from the IPG 102, the PFT 210, and thesurgeon input device 212. In one example, the peripheral interface 192comprises a MICS RF transceiver used to communicate with the IPG 102,the PFT 210, and the surgeon input device 212. As described above, theMICS RF transceiver may utilize a loop antenna for its communications,with other antennas, such as, for example, dipole, chip antennas, orothers known in the art also considered. For example, a communicationslink can be established between the IPG 102 and the secondary displayunit 152, and communications can then occur over a MICS transceiverusing a standard frequency for a medical device transmission.

The IPG 102 includes all the treatment information required for treatingthe patient condition with the electrodes 110, but also includes acommunication interface 192. In one embodiment, the communicationinterface 192 is configured to communicate with one or both of the CP104 and the secondary display unit 152 and convey information includingIPG status, treatment status, program operation, and other informationto the CP 104 and/or the secondary display unit 152. The secondarydisplay unit 152, under the control of the CP 104, may communicate withthe IPG communication interface 192 and may convey new treatmentprograms, including electrode management routines, such as activatingparticular electrodes in a particular order with a particular intensity,by varying amplitude, pulse width, and frequency. Once these treatmentprograms are received, the IPG 102 may execute or respond to thereceived information as directed by the clinician programmer 104 throughthe secondary display unit 152. In one example, the IPG 102 alsocommunicates directly with the peripheral communication interface 178 ofthe CP 104. This embodiment may work well when the IPG 102 is in theproximity of the CP 104 and able to receive information via wireless orwired transmission.

The PFT 210 is sized to be held by a patient and can be used to providefeedback during programming of the IPG 102. In one example, the PFT 210may be used to provide feedback to the CP 104 while a clinicianoperating the CP 104, under instruction from the surgeon, develops theprotocol for the IPG 102. In one example, the PFT 210 is an ergonomichandheld device having a sensor (also referred to as input), acontroller, and a communications output. The sensor can include adiscrete switch and/or a continuously variable input, such as throughthe use of a thermocouple, strain gauge, pressure sensor, piezoelectricdevice, accelerometer, displacement mechanism, or other variable sensingmechanism. It is envisioned that the use of a continuously variableinput can provide magnitude information, thereby providing improvedfeedback information from the patient.

The PFT 210 includes a communication interface 214 that communicatesinformation to the communication interface 188 on the secondary displayunit 152, which relays the information to the CP 104. For example, thecommunication interface 214 and the peripheral interface 192 mayestablish a communication link. Communications can then occur overBluetooth or other wireless formats. The CP 104 may then, ifappropriate, adjust the display imagery on one or both of the primarydisplay screen 168 and the display screen 182 of the secondary displayunit 152 to reflect the patient feedback.

The PFT 210 is used to help the surgeon program the IPG 102 based onpatient feedback. For example in use, the CP 104 activates one or moreof the electrodes (on leads that are connected to the IPG 102) invarious patterns. When the patient feels a sensation as a result of astimulus, such as a stimulus for paresthesia, he or she activates asensor on the PFT 210. The activation of the sensor indicates to theclinician programming system 150 that the patient felt the stimulus andcan also convey the degree of sensation that is felt, depending on thetype of sensor that is employed. Given that there may be a delay fromthe time the patient feels a sensation and activates the sensor, thesystem 150 then re-stimulates the most recently-activated combinationsof electrodes, and the patient again uses the PFT 210 to indicate when(and to what degree) a sensation is felt in order to determine thecombination of electrodes to which the patient was reacting. Furtherdescription of methods for use of the PFT 210 are disclosed in U.S.patent application Ser. No. 13/118,781, filed on May 31, 2011, titled“Device to Provide Feedback For Neurostimulation Programming” (AttorneyDocket No. 029267-9005-00 (QiG 018-US01)), the contents of which areincorporated herein by reference in its entirety.

In some embodiments, the patient may use the clinician programmer oranother portable device (for example an electronic tablet or anelectronic programmer) to draw a pain map and/or a stimulation map. Forexample, referring to FIG. 4, an exemplary user interface 215illustrating the generation of a pain map or a stimulation map 220 isillustrated. The user interface 215 may be displayed through atouch-sensitive screen. The user interface 215 shows a three-dimensionalmodel of a human body, which can be rotated and moved around. Using hisfingers, the patient may be able to paint the pain/stimulation map 220on a region of the human body to indicate the sensation he isexperiencing in that region. During the painting process, the patientmay choose the hue and the intensity of the color of the painted painand stimulation regions to represent the various types ofpain/stimulation or degrees of pain/stimulation. It is understood thatthe pain/stimulation map 220 may also be generated by a healthcareprofessional. The PFT 210 may be used to indicate the intensity ofpain/stimulation, but the maps are displayed either on the clinicianprogrammer (or tablet) or the external monitor.

Referring back to FIG. 2, the surgeon input device 212 is sized andconfigured to be held by the surgeon or other medical care providerwithin the sterile field in an operating room. Using it, the surgeon cancontrol one or both of the CP 104 and the secondary display unit 152.The surgeon input device 212 may permit a surgeon to select particularimages on the display screen 182 of the secondary display unit 152,which may be conveyed to the CP 104. In one embodiment, the CP allows asurgeon to select a particular electrode from an array of electrodes andto select activation including increasing and decreasing amplitude andfrequency. This communication to the CP 104 through the secondarydisplay unit 152 may help reduce the reliance on verbal cues andinstructions passed to the clinician outside the sterile field, allowingthe clinician to rely on more visual instructions simultaneouslyviewable by both the surgeon and the programming clinician. The surgeoninput device 212 includes a communication interface 216 thatcommunicates information to the communication interface 188 on thesecondary display unit 152, which relays the information to the CP 104.For example, the communication interface 216 and the peripheralinterface 192 may establish a communication link, and communications canthen occur over a MICS transceiver using a standard frequency for amedical device transmission. The CP 104 may then, if appropriate, adjustthe display imagery on one or both of the primary display screen 168 andthe display screen 182 of the secondary display unit 152 to reflect thesurgeon input.

In one aspect, this disclosure is directed to a method for displayinginformation on a CP to operating room staff working within a sterilefield. One example of this will be described with reference to FIG. 5.The CP 104 is not a sterile device, so the external connection of thesecondary display communication interface 176 may be used to displaycontent shown on the primary display screen 168 of the CP 104 to thosein the operating room while the CP 104 remains outside of the sterilefield and outside the operating room. Making the content of the primarydisplay screen 168 of the CP 104 viewable by the physician performing aprocedure reduces the interaction required between a physician and theindividual outside of the sterile field assisting the physician byperforming the programming on the CP 104. The physician can easily seethe operating state of the IPG 102 as shown on the CP 104 and does notrequire the individual assisting outside of the sterile field todescribe it. Allowing the physician himself to see the actualinformation on the primary display screen 168 of the CP 104 reduces thetime spent to perform the procedure, as well as reduce the occurrence ofany miscommunications and any resulting undesirable consequences, forexample reducing the probability of an infection.

FIG. 5 shows an operating room 250 and a clinician room 252. These areseparated by a physical barrier, shown here as a wall structure 254. Theoperating room 250 is or includes a sterile field. In the example, showna surgeon performs a procedure on a patient having an implanted IPG 102,and a clinician stands in the clinician room 252 operating the CP 104.The patient holds the PFT 210, and the surgeon holds the surgeon inputdevice 212. In this example, the CP 104 is disposed in the clinicianroom 252, and the secondary display unit 152 and the IPG 102 aredisposed in the surgical room 250. In this embodiment, the CP 104 is atablet controller fitted with a suitable communications port, forexample a micro-HDMI connector. The CP 104 is able to drive a signalover the secondary display communication interface 176 of the CP 104 andcopy the display from the primary display screen 168 on the CP 104 tothe external secondary display screen 182 on the secondary display unit152.

The secondary display unit 152 is, in this example, hung on a wall ofthe surgical room in a fixed location visible to the surgeon and hisoperating staff. In other examples, it may be visible to the surgeon andhis operating staff through a window or other barrier. As can be seen,the secondary display unit 152 is much larger than the CP 104 and isconfigured to be easily viewable by several people at the same time. Inone example, the secondary display screen 182 is at least double thesize of the primary display screen 168 of the CP 104. The secondarydisplay unit 152 includes the speaker 184, the microphone 186, and thecommunication interface 188. Verbal instructions from the surgeon to theclinician are captured at the microphone 186 and emitted from thespeaker 172 on the CP 104. Likewise, verbal responses from theprogrammer can be captured by the microphone 174 on the CP 104 and heardthough the speaker 184. In some embodiments, the contents of the screenof the CP 104 may also be broadcast via a suitable communicationsnetwork.

In the example shown, the secondary display unit 152 is hung via afixation structure 258. Here, the fixation structure 258 is a fixationbracket that extends from a rigid structure, such as the wall, andsupports the secondary display unit 152 in a fixed position. As can beseen, the secondary display unit 152 is tipped at an angle to promotesimple and convenient viewing from the sterile field in the surgicalroom. In this example it is spaced from the surgical area, and may notbe a sterile device itself. It is operated without tactile feedback orinput directly on the secondary display unit 152, and may be considereda hands-free device. It is controlled via the CP 104, but also may relayinformation collected from the IPG 102, the PFT 210, and the surgeoninput device 212. Information is also relayed back from the secondaryinput to the CP display.

The communication interface 188 on the secondary display unit 152, andparticularly the peripheral interface 192 communicates with one or moreof the IPG 102, the PFT 210, and the surgeon input device 212. Asindicated above, in one embodiment, the peripheral interface 192provides two-way communication to each of these devices. In otherexamples, the peripheral interface 192 receives one-way communicationfrom one or more of these devices. The communication interface 188 maybe attached onto or otherwise carried on the display screen 182 or on orwithin its housing.

In the illustrated embodiment, a cable 200 extends from the secondarydisplay communication interface 176 of the CP 104 to an outlet 256 shownon the wall structure 254. In this example, the secondary displaycommunication interface 176 of the CP 104 is a micro-HDMI connector, andthe cable 200 may be an HDMI cable extending between the secondarydisplay communication interface 176 of the CP 104 and outlet 256.

The outlet 254 connects to an outlet 256 in the surgical room 250 via acable within the wall, from which a cable extends to the secondarydisplay unit 152. Over this wired line, the CP 104 communicates displayinformation for presentation on the secondary display unit 152. That is,the CP 104 is able to drive a HDMI signal over the secondary displaycommunication interface 176 of the CP 104 to copy the content from theprimary display screen 168 on the CP 104 to the external display screen182 on the secondary display unit 152. This can also be done viawireless communication. In other words, the wire 200 may not be neededin some embodiments, as the communication between the secondary displayunit 152 and external devices are done wirelessly. In that case, thesecondary display unit 152 may only need a power source or a battery.

In one example, the displayed content minors the information displayedon the CP 104. Accordingly, by viewing the secondary display unit 152,the surgeon sees the same information as the clinician operating the CP104. In another example, the displayed content is different than orincludes additional information than that displayed on the CP 104.Accordingly, with this extended display feature, the surgeon, by viewingthe secondary display unit 152, sees different, but relevant informationthan the clinician operating the CP 104. In one example, the informationshown on the CP 104 and/or the secondary display unit 152 includes IPGstatus information, charge information, program information, status andsettings for one or more electrodes, including frequency, pulse width,and amplitude information for one or more electrodes. It may alsoinclude additional information. In one visualization of the patient'sorgans, x-ray information, or status of the patient's overall conditionincluding items such as vital signs, including blood pressure,temperature, respiratory rates, heart beat, and/or other vitals.

In one example, the secondary display unit 152 is connected to a DigitalVideo Interface (DVI) connector on the CP 104 and the content of theprimary display screen 168 was cloned, copied, or replicated onto thedisplay screen 182 of the secondary display unit 152 via the DVIinterface. In one example, the system 150 achieves 30 frames per second(FPS) when outputting the primary display screen content to an 800×600display screen 182. This is representative of the CP 104 because thedata stream format output by the CP 104 over the HDMI interface may benearly identical to that output from the DVI interface on the EVK.

In one example, the CP 104 requires the user to enable the secondarydisplay screen 182 by selecting a display mode for the external displaymonitor 152. In one embodiment, the hardware for the secondary displaycommunication interface 176 is arranged to detect when the externalsecondary display unit 152 is plugged in or otherwise connected. Usingthis functionality, the CP 104 may detect when the secondary displayunit 152 is connected to the secondary display communication interface176 of the CP 104, the driver in the CP 104 automatically switches toextending the display on the external monitor. Likewise, when theexternal secondary display unit 152 is detached, the CP 104 may disablethe mirroring or extended display function.

Software modules on CP 104 provide instructions for accomplishingparticular tasks handled by the CP 104. In the embodiment describedabove, the software includes a secondary display unit control modulethat controls the image generated on the secondary display screen 182.In one example, the module enables a user to select between twooperating modes. For example, a first mode or mirroring mode may controlthe secondary display screen 182 to show content mimicking that shown onthe primary display screen 164. In this mode, the CP 104 may generatedisplay signals for transmission to the secondary display unit 152 sothat the primary and secondary display screens show the same content. Asecond mode or extended display mode of the secondary display unit maycontrol the secondary display screen 182 to show content different thanthat shown on the primary display screen 164. In this mode, the CP 104may generate display signals for transmission to the secondary displayunit 152 so that the primary and secondary display screens showdifferent content, although some content may still overlap.

The ability to output the primary display screen display to an external,and notably, larger, secondary display unit 152, such as a large screenmonitor or projector, provides a decided advantage when it comes tocommunicating instructions to and receiving verbal responses from aclinician outside the sterile field, such as in another room. Theexternal secondary display unit 152 makes it much easier for the surgeonand others to view what is happening.

FIG. 6 shows another implementation of the system 150 according to oneexemplary aspect of the present disclosure. In this example, the CP 104and the secondary display unit 152 are illustrated being used to displayan image to a number of individuals. The system illustrated may be usedduring instructional sessions, such as during training or education, forexample.

In this embodiment, the CP 104 is a tablet controller fitted with amicro-HDMI connector, and the cable 200 is a HDMI cable extendingbetween the secondary display communication interface 176 of the CP 104and the communication interface 188 of the secondary display unit 152.The CP 104 is able to drive a HDMI signal over the secondary displaycommunication interface 176 of the CP 104 and copies the display fromthe primary display screen 168 on the CP 104 to the external displayscreen 182 on the secondary display unit 152.

In this example, the display surfaces of the primary display screen 168on the CP 104 and the external display screen 182 on the secondarydisplay unit 152 are connected with DirectDraw. Using the DirectDrawAPI, a screen copy is made of the primary display screen 168 on the CP104. A copy of the primarily display screen 168 is then drawn to thesecondary display screen's surface. In one example, the contentsdisplayed on the secondary display screen 182 mirrors that of theprimary displace seen 168. The software routine adds the ability for thescreen to be copied automatically at a user defined rate and for thecopying to be enabled or disabled as necessary.

As discussed above, the CP 104 may require the user to enable thesecondary display screen 182 by selecting a display mode for theexternal display monitor 152, may be arranged to detect when theexternal secondary display unit 152 is plugged in or otherwiseconnected. The ability to output the primary display screen display toan external, and notably, larger, secondary display unit 152, such as alarge screen monitor or projector, provides a decided advantage when itcomes to training personnel because it is much easier for multiplepeople to view what is happening.

In one embodiment, the surgeon input device 212 is not a handhelddevice, but is a motion detector associated with the secondary displayunit 152. In this embodiment, the secondary display unit 152 may includea light source and a camera or sensor to generate a depth map or otherimagery of the surgeon or other health care provider in the operatingroom 250. By detecting surgeon movement, the surgeon input device 212may receive inputs for controlling either the CP or features of thesecondary input monitor 152. For example, a surgeon may be able toselect a particular electrode or an array of electrodes using the motiondetector and increase or decrease the amplitude and frequency of pulsesfrom the electrode or electrode array to create a treatment program thatmay be loaded onto the IPG 102.

FIG. 7 shows one method of activating the display functionality on theCP 104. The method includes querying whether the cable is connected forthe CP to an external monitor, such as the secondary display unit 152,as indicated at step 502. If it is, then the CP 104 operates usingcontrol functionality that mirrors or extends the primary display screen168 of the CP 104 onto the connected display screen 182 of the externaldisplay monitor 152, as indicated at a step 504. At a step 506, the CPmay be used to program the IPG 102 in the manner known in the art.Meanwhile the secondary display unit 152 continues to mirror or extendthe display serene. This continues until the system determines at step502 that the cable 200 is not connecting the CP 104 and the secondarydisplay unit 152. If not connected, the CP is operates to end mirroringor extending CP display onto the secondary display unit 152. So long asthe CP 104 is connected, the functionality of the secondary display unit152 may be utilized. For example, in embodiments using the PFT 210and/or the surgeon input device 212, the CP 104 is configured so thatall functionality is enabled when the CP 104 and the secondary displayunit 152 are connected.

In use, a clinician may take the cable 200 and plug it into thesecondary display communication interface 176 of the CP 104. With thisconnection made the CP 104 can send display information to the secondarydisplay unit 152 for display on the display screen 182. In oneembodiment, over the same cable 200, feedback information from thesecondary display unit 152 can be transmitted to the CP 104. Thisfeedback information may be from the secondary display unit 152, orrelayed through the secondary display unit 152 to the CP 104 from thePFT 210, the IPG 102, or the surgeon input device 212. In addition, theaudio feed between the speakers and microphones on the CP 104 and thesecondary display unit 152 may also be carried over the cable 200. Inother embodiments, the system 150 includes a separate feedback lineand/or a separate audio feed line. In yet another embodiment, thecommunication occurs wirelessly over a direct connection, between the CP104 and the secondary display unit 152, such as, for example, throughinfra-red transmission, or over an indirect connection, such as througha wireless network.

The IPG 102 may then be implanted using methods and techniques known inthe art. The surgeon may give instructions to the programmer of the CP104 to activate or deactivate particular electrodes to develop atreatment program that provides a suitable level of relief to thepatient. Since the surgeon can see the secondary display unit 152, heknows whether his instructions are being properly carried out withoutadditional questions or explanation from the programmer of the CP 104.This reduction in reliance on verbal instructions may increaseefficiently of the surgical procedure. Further, during the procedure,the surgeon may intervene or request additional views of displayedinformation using the surgeon input device 212. This allows the surgeonto have a level of control over the CP 104, although that level ofcontrol may be a lesser level than the level of control of theprogrammer of the CP 104. In one example, the surgeon input device mayallow the surgeon to select an electrode and modify its frequency oramplitude of applied stimulation. Although the patient programmer is notsterile, the surgeon input deice may be a sterile device, and in oneembodiment, is a single-use device that is discarded after use.

During the programming process, information from the PFT 210 may betransmitted to the secondary display unit 152. The secondary displayunit 152 may then relay the received information to the CP 104 forconsideration or processing. Based on the patient feedback, the CP 104may be controlled to update the images on the screens 164, 182 orprovide additional information for programming the implant. Software onthe CP 104 may control the images shown on the secondary display screen182, as described above.

When a stimulation program is set, it may be transmitted to the IPG 102either directly from the CP 104 or it may be transmitted to thesecondary display unit for relay to the IPG 102. The IPG may then storethe treatment program for operation.
